SOURCE: Iphone 2g lock after reset.

Find somebody with an AT&T sim card, put it into the phone and plug it into itunes to get it up an running. Otherwise if your not using AT&T you're gonna have to jailbreak the phone to use it. If your a prepaid AT&T customer, you can activate it but you gotta call AT&T at 800 331 0500

Hello..I have iPhone 3GS..and the problem is up the screen said not service...I open and take the sim and put again in!and nothing..:( please help me!!!what can I do??:(

Is your phone factory unlocked already?
If not, you have to unlock it first to be able to use with any sim card.
If it's just a case of lost signal, toggle the airplane mode off then on.
If this does not work, go to Settings, Reset then Reset Network Settings.

No signal bars on my iphone 3gs 16 gb

first try turning airplane mode on for a few minutes, then back off. its found on the first page of the settings menu near the top. It will cut the link to the cellular network completely, then rebuild it from scratch. I'd say give it at least a few minutes of down time.
if that doesn't work, try a hard reset. hold the power button on top along with the home button until the phone turns off and reboots, then let go and look for service.
if that doesn't work, update your iphone to the latest software. New software frequently contains updates to the software responsible for connecting with the cellular towers.
if no luck thus far, you're destined for the genius bar I'm afraid. good luck

My iphone 3gs is hanging

Normally when resetting a jailbroken iPhone the phone freezes and will not startup. Unfortunately there is no other fix for this issue unless you install the latest software from Apple. 1. Connect the iPhone to your computer. 2. Open iTunes on your computer and click Restore.
This will download the latest software for your iPhone and install it

Everytime i try to sync my iphone 3gs it freezes up when it comes to processing some type of data

Try a reset. Hold down the power key at the same time as the round home key until phone powers down. Release buttons only when you see the apple logo, then wait a min or two for phone to re-boot. You will not lose any data on the phone.
If this does not work, try an actual system reset. Sync iPhone to computer to back up essential data ie contacts apps etc, then go to settings general and reset. Reset all settings as a last resort. This will give you a fresh start and should sort out the majority of any bugs the phone has. A resync with you computer will restore apps etc.
Hope this helps and if so please vote.

My Iphone 3gs has strange signals behavior, it doesn't allways connects to the 3g system but rather to another one, do you know what should i do?

This is known issue with the 3gs, the apple support says it's ok and it knows better to what system to connect in order to have a better signal, but you'd better follow this I guess there will be some updates for this issue
